Belgium I need help identifying (and adding) a Belgian abbey beer

A friend of mine recently went to his native Belgium and brought back some abbey beer for me. I can't seem to find it listed anywhere in the BA database and so I'm hoping to give it a review tonight and add it.

Now, I can't figure out if it was brewed under Van Steenberge or if it is a product of the Rosenberg Abbey. My friend said you can only buy it from the Abbey so maybe Van Steenberge helps distribute it or is some sort of umbrella company?

Anyway, I can't wait to pop the cork on this one (I've had it in my fridge for a few weeks now) but I would like to try and have the full story before I start writing in my journal.

22/06 / '11 WAASMUNSTER (9250) The municipality Waasmunster can show off a brand new aperitif beer: Cuvée Prestige

"We were looking for a new impetus, and therefore immediately thought of an aperitif beer," said Mayor Rick Daelman. "As a church we often give receptions, which always wine being poured. Now we can serve our own aperitif on such occasions."

Cuvée Prestige was special for the town and tourist office VVV brewed by brewery Van Steenberge in Ertvelde, and got the logo with the abbey From Mountain Rose. "It is a light amber colored beer with a full white head", does the label of the 75 centiliterfles salivating. "Cuvée Presige overwhelms you with an aroma of bitter, spicy and malty aromas. Digestif The beer fits perfectly ripe and refined cheeses."
